In order to be suitable for a determination, the end of the titration reaction has to be easily observable. In this case the analyte is an oxidizing agent. This reading can usually be estimated to the nearest hundredth of a milliliter, so precise additions of titrant can be made rapidly. The tablets are stamped out by machines, not weighed individually, and so some variation is expected. List the titrant and indicator you used for each titration. • As titrant is added the concentration of the conjugate to the analyte is increased. Otherwise, an indicator may be added which has an "endpoint" (changes color) at the equivalence point, or the equivalence point may be determined from a titration curve. On the flip side, titration is carried out only by reaction of a single titrant with the solution in which analyte is already present for determining the concentration of that analyte in the solution. The most common use of titrations is for determining the unknown concentration of a component (the analyte) in a solution by reacting it with a solution of another compound (the titrant). An analyte, component (in clinical chemistry), or chemical species is a substance or chemical constituent that is of interest in an analytical procedure. For this specific titration, identify which solution is the analyte and which solution is the titrant. Use pH = –log 10 [H+] to calculate the pH of each of the strong acid mystery … Bestimmung des Endpunktes: Säure-Base-Titration: Zur Bestimmung des Endpunktes einer Säure-Base-Titration wird im Allgemeinen ein pH-Indikator, ein pH-Meter oder ein Konduktometer verwendet.
